25 1) Processor TDP (Thermal design power)
27 Given a fixed frequency and voltage, the power consumption of a
28 processor varies based on the workload being executed. Derated power
29 is the power consumed when running a specific application. Thermal
30 design power (TDP) is an example of derated power.
32 This driver permits reading of registers providing power information
